I have seen the same behavior.
this report needs: * a full backtrace, see: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports * a method to reproduce the crash * better description of what led up to the crash, such as which button was pressed in the dialog to close it.
